CHUCK. n

` Application 'filed January 28,1926. Serial No. 84,462.

rMy invention relates to a chuck deviceQ i My `invention embodies a chuck device, which is adapted to be mounted upon the particularly.designed for' holding the screw-` threaded ends" of nipples, ywhile the opposite ends are being threaded, and to so hold the nipples without liability' of injury to the simple in construction, and embodies only three major parts'. The device is easy to yadjust and will hold the rwork ina powerful manner. f 7

Ink the v accompanying drawings forming a part yof this specification, and in which like numerals are employed to designate like# parts throughout the same,

Figure l is a side elevation of ya chuck embodying my invention,

Figure 21s a transverse section taken on device holding a large' nipple, Y

Figure 3 is a perspective view of one of the jaws, y

` Figure 4 is a side elevation ofthe holding member, L

Figure 5 is a transverse section, takenfoii ythe'same line 2-2 of Figure 1, but showing the chuck device holding a smaller nipple, and v y j Figure 6 is a plan view of one of the jaws. In tliedrawings, rrwherein for the purpose of illustration, areshowii preferred embodi- `in`ents of my invention, 'the numeral 1() 'n it ywill be screwed into the chuck device, v`rand 'its inner end will clamp against the jam iace 12. The plate 31 will also have slidabler contact with the periphery 'of the designates a preferably circular, head or body portion of the chuck device, provided f with a yshank `11, preferably Jformed integral therewith, yalthough it may be rigidlyfattached thereto by any suitable means. The

y `rshank 11 is adaptedto be held within the chuck of a lathe or screw machine, or a vise.

y vT he head is provided upon its front rside with a preferably circular raised jam face 12, the periphery 13 of whichis'preferably slightly tapered. i y n The numeral 14 designates a preferably annular holder, provided upon its rear side with zin/annular recess 15, to Lreceive the raised yface 12. This annular holder is provided with spaced transverse openings 16,

adapted :tor alinement with openings 17,

formed in the headlO, and ythese openings receive clamping bolts 18, having nuts 19.'

The forward side of the ,annular holder 14 My device is` of these webs. are located within these recesses and may be and has openings for the f ybolts18.

'device will receive. suitably unscrewed so that the parts `are is provided with radial recesses 20, within `with screw-threads 22, adaptedL to mesh with the screw-threads 23 upon the nipple 24, the forward end of which is to be screwthreaded. f i

The jaws 21 are provided with ylongitudinal screw-threaded openings 25, for receiving the screw-threaded portions of adjusting bolts 26. The smooth portions of 'these adjusting bolts are rotatable within openings formedin webs 27 of the holder 14, and there are recesses 28 positioned outwardly The headsof the bolts 26 turned fby a suitable wrench. The relative longitudinal vmovement of these adjusting ybolts is prevented by means of stop collars 29, mounted upon the outer portions oi' the bolts and clamped thereby by screws or the like. I n f The ynumeral 31 designates a combined passage of the yAs shown in Figure 2, the nipple 23 is of the maximum diameter that the chuck The nuts 19 may be somewhaty loosened up and the screwthreaded end of the nipple ,is inserted into the chuck device. The jaws 21 are now moved inwardly until their 4screw-threaded ends mesh with the screw threads oi they nipple. 'The nipple may be turned so that nipple, and it is thus seen that the jam face tial that the nipples be held without injury fto the screw-threaded ends thereof. When ythe nuts 19 are screwed up tightly, the bolts 18 will clamp the holder 14 to the head 10, and the plate 31 will also clamp against the jaws 21, holding them against longi- -tudina-l movement. f

In Figure 5, I have shown the chuck as holding a smaller nipple. The jaws 21 are projected inwardly further, but ythe nipple is held in a similar manner, and its inner Ul i end clamped against the jam tace l2, The plate 3l has a correspondingly smaller bore so that it will slidably contact with the periphery or" the nipple, as shown. Y e

lt is to be'undei'stood"that the torms'ot my invention herewith shown and described are to be taken as preferred .examples bt the same, and that various changes in the shape, size and arrangement et parts may be resortedto rwithout departing .from the spirit of my invention or the scope or the subjoined claims. Y f

Having thus described mjf'vinvent-ion, what l claim is LVA chuck device for holding the screwthreaded ends of nipples, comprising a head having a rigid jam face and radial guide means arranged aboutthe jam'tace and poitioned near thesame, radial jaws slidably mounted within the radial guide means and having their inner.y kendsscrew-threaded to mesh withthe threads of the nipple, such` .jam tace, slidable jaws mounted upon the holding member in a group surrounding the inner opening and having their inner ends threaded to engage the threads oi the-nipple,
